Description
The present invention relates to a ceramic heater composition that allows the production at a low temperature, rather than the production method by the high temperature firing of a common ceramic heater.
In general, the most widely used heating element constituting the ceramic heater is a PTC ceramic heater with a ferroelectric barium titanate (BaTiO 3) as a main component and Si, Ti, Fe, V, Cu, Pb, and Sn components It has low resistivity at room temperature and has high resistivity above the transition temperature of ferroelectric material. It has good low temperature characteristics. It has excellent calorific value and fast heating performance of cooling water, which improves winter defrosting and heating effect, and improves quality by extending durability life. It has been used most widely.
However, PTC ceramic heaters are manufactured through high temperature firing of more than 1400 degrees, and due to the slight temperature deviation of the kiln, the characteristic deviation is severe and difficult to manufacture. In many cases, the function of the heater is lost due to voltage and current destruction.
Cracks in ceramic heaters due to electrical breakdown can cause fire.
Therefore, the present invention has been made to solve the above-mentioned problems of the prior art, the present invention is not a manufacturing method by the high-temperature firing of a general ceramic heater mixed with a special solidifying agent inorganic chloride so that it can be manufactured at a low temperature even at room temperature It is possible to produce high-strength ceramic heaters, and also to change the electrical properties through the action of ions and the conversion of atoms, and it is designed to enable the same heat generation while reducing the electricity consumption than the properties of carbon. It is an object of the present invention to reduce the size and to enable high output.
As a technical means for achieving the above object, the ceramic heater according to the present invention is 20 to 30% by weight of alumina cement, 10 to 20% by weight carbon, solidifying agent 1 in a ceramic heater containing alumina cement and carbon and a hardening agent It consists of 10-20 weight% of calcite or stone powder of various kinds of natural stones, such as germanium, and 30 weight%, and carbon consists of natural carbon (carbon, graphite) or processed carbon (carbon, graphite) individually or in mixture. It is done.
According to the present invention, it is possible to obtain the effect of reducing the power consumption by the electrical effect on the carbon as a heat generating material by the change in the electrical properties by the ionic action of the solidifying agent is possible to high power.
Hereinafter, specific contents of the present invention will be described.
The ceramic heater according to the present invention is a variety of natural stones such as alumina cement and 20-30% by weight of alumina cement, 10-20% by weight of carbon, 1-30% by weight of solidifying agent, germanium, etc. It consists of 10-20% by weight of calcite or stone powder, and the carbon is characterized by consisting of natural carbon (carbon, graphite), or processed carbon (carbon, graphite) alone or in a mixture.
When the mixing ratio of alumina and cement is 50:50, the use of cement is high and the high temperature heat generation may require structural problems of cement. Therefore, when manufacturing a heater for high temperature, the mixing ratio of alumina and cement is 70:50. 30 to increase the amount of alumina to reduce the amount of cement used to cope with the problems of cement structure.
In addition, while reducing the amount of cement used by using the keystone or stone powder of the natural stone, it is possible to solidify the heater due to the high-strength expression due to the solidification characteristics of the solidifying agent, and at the same time, it is possible to apply the characteristics of the natural stone such as far infrared and near infrared to the heater.
However, when natural stone is used, it is mixed to the minimum or maximum range where the solid capacity of the cement is not degraded so as not to affect the life of the heater due to the strength degradation problem.
Since carbon has different temperature and resistance characteristics according to the type of carbon, select and mix the appropriate carbon according to the heater's operating temperature and adjust the mixing ratio according to the target temperature and time because the heating rate may be increased or slowed down. Should be made.
